GAS-METER.

Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed November 17, 1905. Serial No. 287.911.

To all whom it may concern:

Be it known that I, FREDERICK SMITH, a citizen of the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Gas-Meters; andI do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in gas-meters.

The object of the invention is the provision of means for facilitating the measurement and passage of gas through a meter.

lVith this and other objects in view the invention consists of certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the claims hereto appended.

In the drawings, Figure 1 is a horizontal sectional view of a meter constructed in accordance with the present invention, taken above the horizontal partitionwhich supports the slide-valves, while Fig. 2 is a similar view showing the slide-valves and their coacting mechanism removed. Fig. 3 is a vertical sectional view taken on line 3 3, Fig. 1. Fig. 4 is avertical sectional view taken on line 4 4, Fig. 1. Fig. 5 is a vertical sectional view taken on line 5 5, Fig. 1. Fig. 6 is a perspec' tive View of one of the slide-valves.

Referring to the drawings by numerals, 1 designates a primary casing, which is of any ordinary structure known to the prior art. The primary casing 1 is provided with a horizontal partition 2, upon which is formed an auxiliary casing 3, within which is formed the valve-chamber or compartment 4.

An inlet-pipe 5 is secured to one side of the primary casing 1, and secured preferably to its opposite side is an outlet-pipe 6.

An intermediate casing 7 is formed upon the horizontal partition 2, and through an opening 8, formed in the primary casing 1, communication is formed through the medium of said intermediate casing 7 with the inlet-pipe 5 and the valve-chamber 4, formed within the auxiliary casing 3.

Apertures 9 9 are formed in the horizontal partition 2. These apertures are provided for the purpose of receiving the ordinary vertical diaphragm-actuated shafts or rods,

which may be connected by any ordinary means to the vertical crank-shaft 10, Figs. 1 and 4.

The valve-chamber 4 is formed in one end of the compartment 11. The compartment 11 is formed within the primary casing 1 above'the horizontal partition 2. Parallel outlet-ports 12 are formed in the horizontal partition 2. Each of said outlet-ports 12 13, which through the medium of an opening 14 in the primary casing communicates with the outlet-pipe 6, Fig. 4. Ports 14 14 open into the diaphragm-compartments 15. Ports 16 16 open into the passages 17. The passages 17 open into diaphragm 18. Ribs 19 constitute valve-seats. Between the parallel inner ribs 20 20 shallow outlet-passages 21 are formed. These passages 21 communicate with the outlet-ports 12.

Each set of ribs 19 comprise a rectangular frame, which surrounds one outlet-port 12, ports 14 and 16, and shallow outlet-passage 21. Upon each set of ribs 19 a slide-valve 22 is positioned. Each slide-valve 22 comprises a hollow body 23, which permits gas to pass either from port 14 into the shallowpassage 21 or from port 16 into said passage. Upon each side of the valve is formed a flat primary extension 24, which is integral with an auxiliary flat extension 25. Theseauxiliary extensions 25 are reinforced by parallel ribs 26 26. The auxiliary extensions 25 are of approximately twice the width of the primary extensions 24. The purpose of the auxiliary extensions 25 is to at all times cover the auxiliary port or outlet-opening 12, so that gas cannot pass directly into said outletport from the valve-chamber 4. Each slidevalve is provided with a transverse rod 27, which preferably extends through the hollow body 23 and is bent, as at 28, near one end for permitting one end of the same to be positioned Within the guide member 29, the opposite end being positioned Within the guide member 30, which is preferably of greater width than the like member 29. Each rod 27 is provided with a vertical extension 31, which is formed with a reduced portion 32. The reduced portion is provided with an aperture which is adapted to receive suitble transverse fastening means for retaining a link 33 in position thereon. The links 33 are secured at one end to the vertical crankshaft 10, Fig. 1. structure, as it is provided with a bowed porcommunicates with a common outlet-p assage Each link 33 is a trussed tion 34, which reinforces the main portion of the link. The crank-shaft 10 is preferably seated in a socketed member 35 at its lower end, and its upper end extends through the top portion of the auxiliary valve-casing 3. The upper end of the shaft 10 is, as heretofore stated, connected by suitable means to diaphragm-actuated rods, (not shown) which are ordinarily positioned within apertures 9 of the horizontal partition 2. When rotary movement is imparted to the shaft 10, the links 33 will be caused to move, and thereby slide the valves 22 through the medium of the rods 27.

Gas is supplied to the valve-chamber 4 through the medium of the inlet-pipe 5 and the intermediate casing 7. From the chamber 4 the gas passes simultaneously into one of the ports 14 and 16. As the ports 14 lead into the diaphragm-compartments 16, the passage of the gas through one of the ports 14 will necessarily fill its diaphragn1eo1npart ment, and as the contiguous port 16 and its passage leading into said diaphragm is closed against the passage of gas from chamber 4 into the same the diaphragm in said compartment will be compressed, thereby forcing any gas contained therein out through the port 16 and into the shallow passage 21 and thence through port 12 and outlet-passage 13 into the outlet-pipe 6, which preferably leads into the house or dwelling main.

It will be obvious from the foregoing description that the ports 14 are formed for the purpose of permitting gas to be exhausted from within the diaphragm into the outletpipe 6 through the medium of the shallow passages 21, ports 12, and outlet-passage 13.

From the foregoing description it is to be noted that in the primary casing a main or common outlet-passage 13 is in communication with the two outlet-ports 12 and shallow passages 21. Upon opposite sides of the passages 21 there is formed a port. The ports formed contiguous to each of the pas sages 21 are capable of being placed in direct communication therewith through the medium of the hollow body 23 of the slide-valve 22. The auxiliary extensions 25 and body 23 of each valve at all times cover one of the outlet-ports 12. The length of each of the outlet-ports 12 is the same as the combined width of one of the ports 14 and 16, one set of parallel ribs 20, and shallow passage 21. While in each valve a port 14 or 16 may be opened so as to permit the passage of gas from the chamber 4 therethrough, the outletport 12 is at all times covered or closed against the direct passage of gas therethrough. The only gas that passes through the port 12 is that which first passes through either port 14 or 16 into the diaphragm-compartment or diaphragm, respectively.
